(AP) — A northwest Iowa woman has been found not guilty for her role in a January car crash that killed a Nebraska woman and her granddaughter.

A Dakota County jury acquitted 28-year-old Heather Reisdorph, of Sioux City, on Friday. She was charged with misdemeanor motor vehicle homicide.

Authorities say Reisdorph’s vehicle was traveling on U.S. Highway 77 near Dakota City when it rear-ended a car driven by 57-year-old Patricia Oldenburg, of Homer, Neb. The impact pushed Oldenburg’s car into oncoming traffic and another vehicle struck it.

Oldenburg and her 3-year-old granddaughter, Regan Coenen, died from their injuries.

An accident investigator who testified in Reisdorph’s defense told the jury he doesn’t believe Reisdorph acted carelessly. She was driving between 46 and 51 mph and swerved to try and avoid the crash.
